Abstract
In samples of industrial anisotropic electrical steel Fe–3% Si, noticeable sheet heterogeneity of its magnetic properties is revealed. This heterogeneity manifests itself in substantial differences in the level of magnetic losses and in the magnitude of magnetic permeability in different regions of the sample under study. It is shown that it is expedient to carry out artificial fragmentation of the domain structure only in regions with the highest magnetic permeability to reduce the magnetic losses in such samples. The application of locally deformed zones in these regions by mechanical scratching leads to a decrease in their magnetic losses by 10–15%, while the value of magnetic losses remained unchanged after the mechanical treatment of other regions of the sample. Such behavior of magnetic losses is qualitatively explained on the basis of domain structure dynamics of Fe–3% Si samples, which has been observed earlier in a series of our previous studies.

摘要
在工业各向异性电工钢 Fe-3% Si 的样品中，显示出其磁性的显着片材异质性。这种异质性表现在所研究样品不同区域的磁损耗水平和磁导率大小的显着差异。结果表明，仅在具有最高磁导率的区域进行域结构的人工碎裂以减少此类样品中的磁损耗是有利的。通过机械刮擦在这些区域中应用局部变形区域导致其磁损耗降低 10-15%，而在对样品的其他区域进行机械处理后磁损耗值保持不变。
